After how many kilometers do car brake pads need to be replaced?

Car brake pads need to be replaced after exceeding 80,000 kilometers. To determine the quality of brake pads, the first consideration is the friction coefficient, which determines the basic braking torque of the brake pads. A coefficient that is too high can cause wheel lock-up and loss of directional control during braking, while one that is too low results in excessively long braking distances. The second factor to consider is safety. Brake pads generate instantaneous high temperatures during braking, especially during high-speed driving or emergency braking. Under high temperatures, the friction coefficient of the brake pads may decrease. An efficient and effective braking system must provide stable and controllable braking force, along with excellent hydraulic transmission and heat dissipation capabilities, to ensure that the force applied by the driver on the brake pedal is fully transmitted to the master cylinder and each wheel cylinder, thereby avoiding hydraulic failure and brake fade caused by excessive heat.
